Current IssueIn Pursuit of Perfection: Defect Reduction
For bare PCB board fabrication, defect reduction is a critical aspect of a company's bottom line profitability. In this issue, we examine how imaging, etching, and plating processes can provide information and insight into reducing defects and increasing yields.
Voices of the Industry
We take the pulse of the PCB industry by sharing insights from leading fabricators and suppliers in this month's issue. We've gathered their thoughts on the new U.S. administration, spending, the war in Ukraine, and their most pressing needs. It’s an eye-opening and enlightening look behind the curtain.
The Essential Guide to Surface Finishes
We go back to basics this month with a recount of a little history, and look forward to addressing the many challenges that high density, high frequency, adhesion, SI, and corrosion concerns for harsh environments bring to the fore. We compare and contrast surface finishes by type and application, take a hard look at the many iterations of gold plating, and address palladium as a surface finish.

Metcal MSA Series Smoke Absorbers
November 8, 2022 | MetcalEstimated reading time: Less than a minute

Metcal, a leader in benchtop soldering systems, announces the release of their new MSA Series smoke absorbers, space-saving compact workbench fans that use activated carbon filters to extract harmful flux fumes and smoke during hand soldering operations.
The Metcal MSA-35L is a versatile dual-position benchtop fan, designed for smaller spaces, which can be used vertically or horizontally for almost twice the airflow efficiency.
The Metcal MSA-25U, a smaller unit than the MSA-35L, features a USB plug which is compatible with any standard 5-volt USB power supply.
“The dual-position MSA-35L and the USB-powered MSA-25U are designed to keep solder station operators safe by drawing smoke and fumes away from the workstation and filtering out impurities,” explains Seerena Wright, Metcal Product Manager. “The MSAs are the perfect addition to any benchtop, even more so when space is limited for soldering operations.”
Both MSA Series smoke absorbers are very quiet when in use, offer easy filter replacement, and are ESD-compliant.

Knocking Down the Bone Pile: Gold Mitigation for Class 2 Electronics
05/07/2025 | Nash Bell -- Column: Knocking Down the Bone PileIn electronic assemblies, the integrity of connections between components is paramount for ensuring reliability and performance. Gold embrittlement and dissolution are two critical phenomena that can compromise this integrity. Gold embrittlement occurs when gold diffuses into solder joints or alloys, resulting in mechanical brittleness and an increased susceptibility to cracking. Conversely, gold dissolution involves the melting away of gold into solder or metal matrices, potentially altering the electrical and mechanical properties of the joint.
